Hi,

https://conversejs.org/fullscreen.html
no longer works for my
installed unofficial (by wg9s) De SeaMonkey 2.53.6 beta 1 pre 
Mozilla/5.0  (NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0 
Build 20201115220004 (Normal User Profile and also with newly created 
User Profile, Default Classic Theme) on German WIN7 64bit

Only shows blue (or so) empty screen instead of white screen with login 
dialog.

Error console shows:

I can't tell whether related or not.

Of course I tried FF compatibity, older versions, ...
So seems not to be a SM regression, but incompatibility with SM and 
latest Page versions. Page worksfine with EDGE and Trox and probably 
most other browsers.

Similar problems with

Any Ideas how to get that working again?

I had a similar problem with the Web site of Unify Financial Credit
Union, only the screen was pale lavender.  They told me I should switch
my browser to Chrome.  Instead, I am switching credit unions.

Definitely. With a Custom Elements polyfill, the page appears as you 
expect. I guess that not having Custom Elements could cause the XML 
syntax error too. As discussed previously for github.com:
